No. 228,659. Y Patented .lune 8.1880a r Humm @www UNITED STATES To allwhom it may concern Beit known that I, GEORGE M. MARKS, of Fowler, inthe county of Centre and State of Pennsylvania, have invented certainnew and useful Improvements in Sulky-Blows; and I do hereby declare thatthe following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification, and in which- Figure l is aplan or top view of a sulkyplow embodying my improvement. Fig. 2 is aside elevation of the same. Fig. 3 is a rear elevation; and Fig.isasectional view through line .r x, Fig. 3, showing the wheel-adjustingdevices.

Similar letters of reference indicate correspondin g parts in all thefigures.

My invention has relation to sulky-plows; and it consists in theimproved construction and combination of parts, as hereinafter morefully described, and particularly pointed out in the claim.

In the drawings, A is the central beam, and A A the converging sidepieces of the sulkyframe, the diverging rear ends of which are united byan upper and a lower cross-piece, B C, to which they are securelybolted. D is the drivers seat, which is secured upon therearwardly-projecting end of the middle beam by a spring standard orbracket, d.

E E are the plow-beams, (two or more in 11umber,) which are made of woodor iron, of a curved shape, as shown in the drawings, with their forwardends pivoted between the converging ends of the pieces A A A upon abolt, a, their rear ends carrying the shovels E E', which may be of anydesired size, shape, or construction.

F F are elbow-levers, each of which has its fulcrum in a short standard,b, upon the upper cross-piece, B. f is a rod or chain which connects theupper short arm of each of the elbow-levers F with one of theplow-beams, E, so that by operating the long arm of lever F the beam,with its shovel, is raised or lowered. It may be retained in thiselevated position by means of hinged catches c e, which lock the leversF in place in their depressed position.

Each of the wheels G G has a square stubaxle, H H, which is insertedthrough hang- PATENT OFFICE.

ers l1, h, projecting downward from and bolted upon the lowercross-piece, C, of the sulkyframe. Bolted upon each of the stub-axles HH, between its pair of hangers h h, is a attened rod or strap, I, whichpasses up through slots in the upper cross-piece, B, and is secured atits upper end in a lever, K, having its fulcrum in the front side of thecrosspiece B at c.

The adjustable standards or bars I I have notches i2 ou one side, toengage with the pivoted pawls i i, by means of which said standards'maybe held in any given position.

From the foregoing description, taken in connection with the drawings,the operation and advantages of my improved sulky-plow will readily beunderstood.

The shovels may be set at any desired pitch and depth in the groundsimply by operating the levers F F, either by the hands or feet of thedriver, and the wheels are adjustable in like manner by operating leversK K, all the levers being within easyreach of the drivers seat.

By this construction the plows can be elevated so as to pass over stumpsand other obstructions in the eld, and the sulky-fraine may be tilted byoperating one of the levers K, so as to be used for hill-side plowingwith the same ease and facility as for level plowing. Hence my improvedplow is adapted for any kind of ground and any condition of soil, and asthe frame consists of few parts simply put together, it is not liable tobreak down or get out of order, even with the roughest usage.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- In a wheel-cultivator, thecombination of the axle C and the two pairs'of guide-hangers h h withthe wheel-spindles H H, the sliding bars I I, having notches 2, thelevers K K, passing through the bars I, the pawls fi fi, and the frame AB, substantially as shown and described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
